Hello,

on searching for discrepancies in my dashboard I was able to cut down the problem to the following to searches. Maybe there is an explanation for it. The difference is in the count of TLSv1.2.
search with eval

search without eval

Hi @gesa_behrens,

This is happening because a single transaction contains sometimes more than one ssl_protocol field values which means that if the condition matches on "-" everything gets replaced by the "HTTP" string.

You might want to run your eval before building the transaction then you'll be good on the count.

Cheers,
David
